GENETIC DIVhRGENCE IN INTERSPECIFIC HYBRIDS OF SUGARCANE

Abstract

Forty six interspecific hybrids of sugarcane derived from
crosses involving various species were evaluated and grouped
into eleven clusters, indicating high genetic diversity among them.
Though there was no clear cut differentiation between clusters
with reference to species, to some extent, dispersion of hybrids
in various clusters was in accordance with their species origin.
Based on inter-cluster distances and cluster means for various
characters, potential parents were identified from different clusters
for hybridization programme.
